I agree Nick, demo as much as you can. I was a tried and true O’Brien guy but on a whim I skied a Connelly and it fit me great. If you can't demo I would lean toward the F1X (obvious bias though). The Concept is very forgiving but the F1X is faster and turns a bit harder. And being a mildly shaped ski it will perform well at the slower speeds but also is solid at 36. Give them a try if you can, can't go wrong either way.
